Compared with the prior art, it can effectively remove steel slag on the track.

[0004] However, in the above-mentioned existing track sweeper, its plow-type slag pusher is in rigid contact with the slag. Once it encounters a large volume of slag, it is easy to cause a sense of frustration to the vehicle, especially when the vehicle runs at a faster speed, which is more obvious, and is not conducive to the stable operation of the vehicle. At the same time, the rigid collision is easy to be damaged, reducing the service life.

[0005] Therefore, it is urgent to design a novel reinforced track sweeper for scrap steel straddle carrier to solve the above-mentioned technical problems. Utility Model Content

[0017] 2. The track sweeper of the utility model adopts a flexible structure for the second cleaning component. When larger debris comes into contact with the baffle, the baffle will be subjected to the force to squeeze the buffer spring, thereby achieving a flexible collision between the baffle and the debris, avoiding the problem of frustration caused by rigid collision, and being able to improve the stability of vehicle operation while extending the service life of the track sweeper; and the front end face of the baffle adopts an inclined surface extending obliquely toward the outside of the frame, so that the highest point of the inclined surface of the baffle comes into contact with the debris first, and as the baffle moves forward, the debris will be squeezed and tilted until it falls on the outside of the track, making it more convenient to clean up the debris later.

[0018] 2. The track sweeper of the utility model has a first cleaning component which is a detachable mounting structure, which is convenient for disassembly and maintenance. At the same time, the steel wire is installed on the base, and the base is connected to the base through an adjusting bolt.
